I'll say that I would be very hesitant to examine any particulars of his wording. He does not speak fluent English and it should be obvious that + assistance from machine translation can easily bring in words with unintended connotations. I can also have some amount of understanding for him definitely being hit by "anti-censorship" GG-types over this, and now having to try to understand what's actual criticism and what's fake in another language and context (EDIT: context being gamergate and not about the actual topics involved, to be clear).
That being said... the overall message is still obviously disappointing to say the least, and it hurts to see things go this way. It sure is something to immediately burn what good will you'd earned from saying you were going to fix things. What got changed seems weirdly implemented from the little I saw, so I don't know how much ability they had for getting line changes/re-recording done and if that affected what was done, but if that was an expected limiting factor he could have said as much previously and not acted like it's fine and the transphobia that remains is intended now. Especially when there was the understanding that they'd be getting some help with doing the fixes correctly... and, along those lines, someone with stronger English who is more directly involved with the line by line English writing should probably be handling talking about the changes being made.
